目前我们期望能够将存储于tugraph的某些指定的点/边类型的全量数据,导出到csv文件中,文件中内容的组织形式为宽表的形式。
(例如点类型Film定义了id、name、description、director这4个属性,希望导出的csv文件包含所有Film类型的点数据,并且分别有4列,对应id、name、description、director这四个字段)

我们希望tugraph可以提供封装功能完备、或者具备相关能力的API。

使用neo4j driver 连接tugraph,直接发送cypher 语句 "match (n) return n" 就可以了。结果是流式返回的,不管多少数据都可以读出来,不会引发内存oom。
